Active noise control ( ANC ), also known as noise cancellation ( NC ), or active noise reduction ( ANR ), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Noise, vibration, and harshness ( NVH ), also known as noise and vibration ( N&V ), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with ...
Active sound design is an acoustic technology concept used in automotive vehicles to alter or enhance the sound inside and outside of the vehicle. Active sound design (ASD) often uses active noise control and acoustic enhancement techniques to achieve a synthesized vehicle sound. The typical implementations of ASD vary, from amplifying or ...
Industrial noise control is a subset of interior architectural control of noise, with emphasis on specific methods of sound isolation from industrial machinery and for protection of workers at their task stations. Sound masking is the active addition of noise to reduce the annoyance of certain sounds, the opposite of soundproofing .
For many of us, it’s a fact of life that as you get older, you start forgetting things more often. Maybe you get to the car and find that you’ve forgotten your keys. Maybe you get to the car ...
Acoustical engineering. Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration. It includes the application of acoustics, the science of sound and vibration, in technology. Acoustical engineers are typically concerned with the design, analysis and control of sound.
A soundscape is the acoustic environment as perceived by humans, in context. The term was originally coined by Michael Southworth, [1] and popularised by R. Murray Schafer. [2] There is a varied history of the use of soundscape depending on discipline, ranging from urban design to wildlife ecology to computer science. [3] An important ...
Screen size varies from 5-inch to 7-inch for the double Din car stereos. Active noise control and noise synthesis. The automobile sound system may be part of an active noise control system which reduces engine and road noise for the driver and passengers.
